Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Puff-paste, French
Ingredients
Directions
Make the dough
Sift the flour and make a large hole in the center.
Add a pinch of salt, small pieces of butter, and egg yolks into the hole.
Use cold water to dissolve the salt.
Mix until the paste is the same consistency as the butter.
Work the flour lightly.
Form the mixture into a large ball.
Flatten the ball quickly.
Laminate with butter
Lay butter on the table with a little water.
Extract the liquid from the butter.
Squeeze the liquid into a clean towel.
Place the ball of butter over the paste.
Flatten the butter with a cloth.
Fold the paste around the butter in a square shape.
Roll and fold
Dust the table and the paste with flour.
Roll the paste smooth with a rolling pin.
Fold the paste in thirds.
Roll it out again.
Dust with flour to prevent sticking.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the gluten network that gives the dough its structure.
- Butter
- Forms separate layers that steam apart in the oven, producing flakiness.
- Egg yolks
- Add richness and fat, and help bind the dough.
- Cold water
- Dissolves the salt and moistens the dough without warming the butter.
The step that matters
Keeping the butter cold and in a flat sheet while laminating. If the butter softens and melts into the dough, the layers blend together instead of separating, so the pastry loses its flaky rise. Keeping the dough and butter cold between folds keeps the layers distinct.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
